ryans We are trying to solve this right now, we got the suggestion from a member of this website

    Gurm What you have to do to remove flicker with Iris is to basically turn your monitor (hardware) brightness to 100%. Then you can control your brightness level from Iris (with software). It controls the brightness a little bit differently and that's why it's possible to eliminate the flicker

      Hello and welcome,

      My 2 cents: I am not sure blue light filtering is the best direction to go in, as flux already does this for free, and PWM free monitors are now common place - though a laptop solution would be welcomed. If you want to get my money, software that stops temporal dithering for AMD or Nvidia graphics cards, or android phones would do it.

      Are you familiar with Suguru Kawamoto's work? he created software that prevents modern intel integrated GPUs from dithering, something I rely on to use computers comfortably. However I understand that without recognition that such things are problem, marketing this software would be difficult.

          Seagull I'm doing some of my own research at the moment related to this. Don't have anything to share yet and I'm busy with university as well.

            AGI I personally find Iris more advanced, for example, it can auto change your blue light value based on time of day/night in where you live in by using approximation (basically taking the city/country you live in), while flux is only locked to the position of the sun and uses geolocation which takes your exact coordinates and feels like a privacy issue for me.
            It has locked blue light values, with Iris you have full control 0K-6500K and you can choose
            Iris has Types, which are like presets made from us. We have Health (general usage), Sleep, Programming, etc. You can also invert the screen and have dark mode on whatever you want 😃

            We actually have an article on this, you can check it here:

                hpst I mentioned it at a previous reply but right now we are trying to solve the temporal dithering. I wouldn't say that our company is about following the money and ripping off clients, as a matter of fact, we try to help every client and make them happy.
                We've made changes and added custom features due to client requests, for example here we have a lot of features that exist solely because a user wanted them:

                    Pernichev If you could do a lifetime multi PC subscription (I think $50 is reasonable given how there is a trial and all) I think that would be a better product.

                    Hmm.

                        Seagull Yes, we are aware of his work, thanks

                        Iris is trying to solve the headaches from computers for the masses that are not aware of what flickering is and what blue light does to them and help them

                          Pernichev I mentioned it at a previous reply but right now we are trying to solve the temporal dithering. I

                          Well that is certainly good news. Is your dithering solution going to be available for Linux? What is the basic theory you are chasing to toggle dithering? As I have been told it would require drivers for each vender to be altered. Do you have a time frame?

                          My comments were born of cynicsm and lots of negative experiences combined with misery from this problem. My apologies if it felt personal. That said many of us are desperate enough to be held ransom and pay whatever one might charge, but if there is a solution forthcoming I'd prefer to see it be open sourced and not a proprietary product. I have no problem donating, paying, or putting up bounties...but I do not like closed software that makes me dependent on you forever since companies come and go and this matter is too important of an accessibility issue to hinge on one "secret sauce" that may or may not be there long term for us if nobody can fork it, continue development etc. Personally the dithering solution is the only bit I am interested in and I wouldn't use the other existing features.

                              Pernichev Thanks on reply and link.

                              I found out about dithering on this website. From the little I understand it is not universally acknowledged to be a problem, as flickering or blue light. The big guys in the electronics industry would probably say ours are just speculations. You are working on eliminating such a feature though. Could you disclose why you believe it is a source of eyestrain?

                                  hpst AGI
                                  I actually think that with the PWM Flicker removal you eliminate most of the eye strain anyway, enough to make it a pleasant experience. What we want from Iris is to be the best possible when it comes to saving eyes so that's why we are going to try adding it right now.

                                  I created a form and right now we are collecting feedback on the dithering issue so we can have the right approach when fixing it and make what you guys expect possible. So, if you can, take the time to fill it out so you can help us:

                                        Strongly disagree with this statement. I have just as much strain on known PWM free panels and have tested this extensively, same with blue light entirely blocked with lab glasses, as I do any other time. My most comfortable panel has PWM. For most people I have talked to its irrelevant to their strain. I do not believe PWM is that big of a problem and rather a red herring most times. There is definitely something else going on and dithering is the only likely theory I have heard. We just cant shut it off reliably to test.

                                        With regard to your survey about dithering the answer to what we want is simple...to be able to turn if off across all major operating systems/gpus. My personal needs are Linux and Android, but Windows, MacOS and iOS solutions will be needed by users here as well.

                                        I can also confidently say people will want it to be open sourced (that doesn't mean we won't pay for it) because this is a serious accesibility issue and not just an entitled feature request, many of us are losing our livelihoods and only opportunities because of it, and any solution cannot be dependent on an unreproducable proprietary code that is lost if your company pivots, closes, lets the solution rot etc. Things happen but this is too important so if a solution IS found, for the greater good it needs to be available.

                                            hpst iOS might be impossible without collaboration from Apple since without a jailbreak you can't load your own drivers on the device.

                                            hpst For most people I have talked to its irrelevant to their strain

                                            It's certainly relevant to mine, and I feel even in cases where it's not the primary factor it's just "pouring gasoline on the fire"

                                            I otherwise agree with your post though.

                                                  JTL Sorry, should have phrased it better and not said "irrelevant" as a blanket term. I didn't mean it's not an additive problem, rather that simply removing it from the equation doesn't cure people across the board from my reading, meaning there has to be something else going on as you know. If something is a root cause then removing it would have clear and omnipresent results across HW and OSes and use cases and we just haven't see that with anything so far. I just get frustrated when someone says "just removing PWM/bluelight/blinking more etc removes most strain and makes things usable" as this is provably not true. I am also of the strong belief that we will see more and more people like us because everyone is using Gunnars, F.lux, avoiding PWM per notebookcheck reviews etc and thinking they are solving their problem but the placebo or minor additive issue removal will stop working and that evil root problem will manifest but will be blamed on office lighting, CVS, or whatever else is the next red herring.

                                                    @JTL I see that you are a moderator so Is it okay if I post the google form as a separate post so we can get more feedback from the people and try to make it an actual thing?

                                                      Pernichev I'll let @Slacor (Forum owner) comment on that. I don't feel that I'm qualified to make the decision without his input.

                                                        Users created forms to collect data is fine, if there's malicious (spam / scamming) content then those will need to be removed.

                                                        Pernichev feel free to create a separate discussion

                                                        Alternatively, the original post can be modified to give the form more visibility

                                                          Thank you for coming here. I have left a few messages on Daniel's facebook about this issue and he was always quick to reply. Being able to turn off temporal dithering would be a blessing, as it would prove/disprove that its a problem. Many people here now encounter that on a safe system, certain applications are straining and unusable. For me on a good laptop with win 7 such app is the new firefox. Whether and how its taking over the display rendering is a mystery to me.
                                                          I dont believe theres something wrong with new tech, as millions are fine. But it does something differently and an unlucky minority of us has extreme reactions. I believe whatever it is, it disturbs eye teaming and accomodation of eyes. Whether that is completely fixable is still an open question for me. About 5-10% of people have hidden eye teaming and accomodation trouble, so it would make sense such minority is affected.
                                                          In VR, this issue is well known - https://packet39.com/blog/2017/12/25/the-accommodation-vergence-conflict-and-how-it-affects-your-kids-and-yourself/
                                                          However I believe even in non VR new display technology and rendering, something like this is taking place.
